How would the outcome of the investigation change if both objects were rubbed on the cat's fur? Use evidence and scientific reasoning. This time, a student repeated the Styrofoam ball experiment. The student rubbed the plastic rod on the cat's fur, but also rubbed the Styrofoam ball on the cat's fur. Be sure to describe the field interactions for both objects and describe the charges.

Jen is conducting an experiment involving a device known as a pith-ball electroscope, shown below. The plastic ball of the electroscope hangs in midair and is uncharged. Charges cannot move along the silk thread that holds the ball in the air. Jen completes the following steps in her experiment: 1- She collects three identical, uncharged rubber tubes. 2- She holds a magnet to the first tube for 5 minutes. 3- She submerges the second tube in a tank of water for 5 minutes. 4- She rubs the third tube with animal fur for 5 minutes. Jen's teacher tells her that she can use the pith-ball electroscope to see if any of the rubber tubes are surrounded by an electric field. What should Jen do to test for an electric field surrounding each tube?

9. A plastic rod is rubbed with a piece of animal fur. The plastic rod acquires a negative charge during this process. Which of the following is true about the charge on the piece of fur? A. It acquires a positive charge but greater in magnitude than the rod B. It acquires a positive charge but less in magnitude than the rod C. It acquires a negative charge but greater in magnitude than the rod D. It acquires a negative charge but less in magnitude than the rod E. It acquires a positive charge with the same magnitude as the rod 10. A positively charged rod is brought close to one end of a neutral metallic plate. What type of charge is induced on the closest side of the plate? A. Positive B. Negative C. Neutral D. It depends on the separation between the rod and plate E. More information about the type of metal is required 11. A positively charged rod is brought close to one end of a neutral metallic plate. What type of charge is induced on the farthest side of the plate? A. Positive B. Negative C. Neutral D. It depends on the separation between the rod and plate E. More information about the type of metal is required 12. A neutral electroscope is touched with a negatively charged rod. What is the charge on the electroscope after the rod is removed? A. Positive B. Negative C. It stays neutral D. It depends on the contact time E. It depends on the material that the electroscope is made of 13. A neutral electroscope is touched with a positively charged rod. After the rod is removed, the electroscope is charged positively because of: A. Induction B. Conduction C. Thermo-emission D. Photoemission E. None of the above
